As adults, alba meowls are loyal companions, closely bonded with their magi. Although they prefer their magi's company, they also enjoy playing with one another and are a source of mischief in the Keep, chasing and batting playfully at anything that catches their eye. They are notorious beggars and will steal from plates or larders if not carefully watched, so they are not allowed in the Keep's cafeteria or kitchen. Despite their mischievous personalities, they love to sit quietly with their magi next to a warm fire in the evenings.

Alba meowls are small creatures, no larger than a common housecat. The brown parts are small feathers, while their white underparts are fluffy fur, and they go through a molt and a shed once a year. They are friendly, affectionate and independent in addition to being easy to keep. They can make a wide range of noises from meowing to shrieking, and are quite talkative. Alba meowls are curious and are especially fond of romping through gardens, where they menace grass and eat the flowers. They are easily amused and enjoy toys they can chase after, like balls. All told, they are radically different in personality from their cousin, the darker and far less friendly Tenebricosa meowl.
